Truth, though still speculation. If we presume Nero to have been born around the time of the Temen-ni-gru incident, then him being 16 or 18 now would make Dante around about 35, which still fits the timeline. Of course, we could say there was time travel or alternate dimensions involved, which would make any age possible.
